Calendar Insights charts your week in living color: it links to every calendar you use, syncs in seconds, and funnels each event into a single, scroll‑free dashboard that totals hours by category—work, family, rest, learning—then displays them as bright rings, heat‑map blocks, and trend lines you can tap for instant drill‑down. Quick filters surface late‑night work sessions or missed workouts; one‑touch exports send weekly or monthly reports to PDF or CSV; privacy‑first design keeps all data on your device. Swipe right for a Goals view that compares planned hours to actual time, tap a day to replay it hour by hour, or long‑press any slot to re‑tag, duplicate, or reschedule. With Calendar Insights you don’t guess where the week went—you see it, shape it, and send the next one where you want it to go.

From a simple "Background Music" to your new "Focus App." Nook is a virtual coworking space where you can immerse yourself in your work while feeling the gentle presence of others, wrapped in soothing ambient sounds like a crackling campfire or ocean waves. Say goodbye to the loneliness of remote work or late-night studying. Nook creates a cozy, highly focused environment right on your phone—just like sitting in your favorite cafe or a quiet library. 【 What is Nook? 】 It’s a virtual focus room designed for silent shared experiences. ・ Choose your favorite environment (like a Campfire or Beach). ・ Find an empty seat and claim your spot. ・ Dive deep into your tasks. You'll share the space with others who are also working hard. There is no direct chat, no voice calls, and zero pressure to socialize. Just the comforting feeling of "someone is here with me," giving you that gentle push to stay focused. 【 The Perfect Distance: Body Doubling 】 Every few minutes, someone might walk in to start their session, or quietly pack up and leave. Occasionally, a tiny bubble with a brief status update floats by. This subtle sense of connection serves as a perfect "body doubling" experience, melting away the isolation of working alone without the distraction of social media. 【 Aesthetic & Immersive Design 】 Designed with warm, neutral tones and a minimalist aesthetic. The gentle, unobtrusive animations enhance your immersion without breaking your concentration. 【 Key Features 】 ◆ Cozy Spaces ・ Curated ambient sounds tailored to your mood. ・ A distraction-free UI that keeps you grounded. ・ A loose, stress-free connection with others sharing the same room. ◆ Identity & Seat Selection ・ Pick your seat in beautifully crafted isometric rooms. ・ Set up your "Identity Card" to share a quick status with the room. 【 Perfect For: 】 ・ Those feeling isolated during remote work or studying. ・ People who get distracted easily and need the "presence of others" to focus (Body Doubling). ・ Lovers of cafe or library atmospheres. ・ Anyone tired of exhausting social media notifications or forced communication. ・ Users who want to put their phone down and stop doomscrolling. 【 Premium Plan 】 Nook offers a Premium Plan for users who want to elevate their focus environment (Basic features are completely free!). ・ Unlimited access to all Room Types. ・ Completely ad-free experience. ・ Early access to upcoming features. Subscriptions will automatically renew unless canceled at least 24 hours before the end of the current period. You can manage and cancel your subscription in your App Store account settings. Privacy Policy & Terms of Use: https://note.com/kojiro79/n/n7c8899db1c9b 【 A Note from the Developer 】 Nook is an indie app built with a lot of love. Your reviews and feedback are what keep this project going and growing! If you have ideas like "I wish there was this kind of room" or "This feature would help me focus better," I’d love to hear them. Let's make our solitary hours richer and more focused. I hope Nook becomes a quiet, supportive companion in your daily routine!
